Functional Features

1. Voltage Monitoring: The MAX16035PLB46+ continuously monitors the power supply voltage and compares it to the user-adjustable threshold.
2. Reset Generation: When the monitored voltage falls below the threshold, the IC asserts the RESET pin low, indicating a reset condition.
3. Fixed Timeout Period: The reset signal remains asserted for a fixed duration of 140ms after the voltage rises above the threshold.
4. Adjustable Threshold: The reset threshold voltage can be set by connecting external resistors to the appropriate pins.
5. Power-On Reset Delay: The IC provides a 20ms delay before generating the first reset signal upon power-up.

Advantages and Disadvantages

Advantages: - Low-power consumption ensures minimal impact on overall system energy efficiency. - Wide operating voltage range allows compatibility with various power supply configurations. - Adjustable reset threshold enables customization for different system requirements. - Small form factor facilitates integration into space-constrained designs. - High accuracy ensures reliable voltage monitoring and reset generation.

Disadvantages: - Fixed timeout period may not be suitable for all applications requiring longer or shorter reset durations. - Lack of built-in hysteresis may result in multiple reset signals during voltage fluctuations near the threshold.

Working Principles

The MAX16035PLB46+ operates by comparing the power supply voltage with the user-defined threshold voltage. When the voltage drops below the threshold, the IC generates a reset signal by asserting the RESET pin low. This signal remains active for a fixed timeout period of 140ms after the voltage rises above the threshold. The adjustable threshold allows customization to suit specific system requirements.
